Freshman 15: valid theory or harmful myth?

The authors investigated whether the perception that freshmen gain 15 pounds during their 1st year of college is related to either actual or perceived weight gain. Forty-nine incoming freshmen at a small liberal arts college completed the study by filling out questionnaires and health data at the beginning and end of their 1st year on campus. The findings revealed no significant weight gain at the end of the year. The "Freshman 15" myth was found to play an important role in perpetuating negative attitudes toward weight. Freshmen who were concerned about gaining 15 pounds were more likely to think about their weight, have a poorer body image than others, and categorize themselves as being overweight.     

Unmasking the Trend Sought by Jonckheere-Type Tests for Right-Censored Data

Medical and epidemiological studies often involve groups of subjects associated with increasing levels of exposure to a risk factor. Survival of the groups is expected to follow the same order as the level of exposure. Formal tests for this trend fall into the regression framework if one knows what function of exposure to use as a covariate. When unknown, a linear function of exposure level is often used. Jonckheere-type tests for trend have generated continued interest largely because they do not require specification of a covariate. This paper shows that the Jonckheere-type test statistics are special cases of a generalized linear rank statistic with time-dependent covariates which unfortunately depend on the initial group sizes and censoring distributions. Using asymptotic relative efficiency calculations, the Jonckheere tests are compared to standard linear rank tests based on a linear covariate over a spectrum of shapes for the true trend.     

Does Difference Make a Difference in Financial Planning for Risk?

Current policy‐making assumes people perceive and respond to financial risk in a uniform and rational way. This research sought to investigate whether social and cultural differences along the dimensions of disability, sexuality, faith and ethnicity influence attitudes to money and approaches to planning for possible financial risk eventualities. Eighty in‐depth interviews with individuals committed to different faiths (Muslim and Christian), disabled people, gays, lesbians and bisexuals, and members of black and minority ethnic groups (black and Asian) were conducted in 2005/2006. Mainstream cultural reference points were dominant in respondents’ accounts; however, difference was also found to be more determining in some areas than has previously been documented. The article explores the impact of these relationships on financial planning and draws out the policy implications of the different elements of difference on financial planning. The study argues that socio‐cultural approaches to risk need to be better understood at the policy‐making level.
